Comment:
This issue is still ongoing. Every webkit2gtk-based browser I have tested (badwolf, netsurf, surf, epiphany) fails in the exact same way: skipping an ad, pausing, rewinding or fast-forwarding on YouTube, Odysee, DTube, PeerTube or Dailymotion causes the video stream to hang and the entire browser tab to freeze. 

Interestingly, playing, pausing, rewinding and fast-forwarding VP8 webm files and Ogg Theora ogv files from Wikimedia works correctly without issue - the problem only seems to affect h264/h265 streams. 

Playing, pausing, rewinding, and fast-forwarding the above-referenced VP8 test file with gst-play-1.0 locally works perfectly.  Playing, pausing, rewinding, and fast-forwarding a h264 test file with gst-play-1.0 locally works perfectly. Playing, pausing, rewinding, and fast-forwarding a direct video URI from DTube (right click the video, click "copy video link location") with gst-play-1.0 also works perfectly. Playing, pausing, rewinding, and fast-forwarding the same direct video URI in the browser also works perfectly. However, when playing the video from the DTube website (i.e., just loading the DTube URL and clicking play instead of right clicking and getting the direct video link location), the video hangs and the tab freezes when pausing, fast-forwarding or rewinding. Quite frustrating. This does not affect non-webkit browsers such as Firefox, Chromium, Basilisk, or Pale Moon; those browsers obviously do not use gstreamer for their backend, which seems to be the source of the problem.

My installation: glibc, kernel 5.11.18_1, gstreamer1-1.18.4_1, gstreamer-vaapi-1.18.4_1, gst-libav-1.18.4_1, gst-omx-1.18.4_1, gst-plugins-base1-1.18.4_1, gst-plugins-good1-1.18.4_1, gst-plugins-bad1-1.18.4_3, gst-plugins-ugly1-1.18.4_2, webkit2gtk-2.32.0_3
